An annotated guide to program and develop GNU/Linux Embedded systems quicklyAbout This Book* Rapidly design and build powerful prototypes for GNU/Linux Embedded systems* Become familiar with the workings of GNU/Linux Embedded systems and how to manage its peripherals* Write, monitor, and configure applications quickly and effectively, manage an external micro-controller, and use it as co-processor for real-time tasksWho This Book Is ForThis book targets Embedded System developers and GNU/Linux programmers who would like to program Embedded Systems and perform Embedded development. The book focuses on quick and efficient prototype building. Some experience with hardware and Embedded Systems is assumed, as is having done some previous work on GNU/Linux systems. Knowledge of scripting on GNU/Linux is expected as well.What You Will Learn* Use embedded systems to implement your projects* Access and manage peripherals for embedded systems* Program embedded systems using languages such as C, Python, Bash, and PHP* Use a complete distribution, such as Debian or Ubuntu, or an embedded one, such as OpenWrt or Yocto* Harness device driver capabilities to optimize device communications* Access data through several kinds of devices such as GPIO's, serial ports, PWM, ADC, Ethernet, WiFi, audio, video, I2C, SPI, One Wire, USB and CAN* Practical example usage of several devices such as RFID readers, Smart card readers, barcode readers, z-Wave devices, GSM/GPRS modems* Usage of several sensors such as light, pressure, moisture, temperature, infrared, power, motionIn DetailEmbedded computers have become very complex in the last few years and developers need to easily manage them by focusing on how to solve a problem without wasting time in finding supported peripherals or learning how to manage them. The main challenge with experienced embedded programmers and engineers is really how long it takes to turn an idea into reality, and we show you exactly how to do it. This book shows how to interact with external environments through specific peripherals used in the industry. We will use the latest Linux kernel release 4.4.x and Debian/Ubuntu distributions (with embedded distributions like OpenWrt and Yocto).The book will present popular boards in the industry that are user-friendly to base the rest of the projects on - BeagleBone Black, SAMA5D3 Xplained, Wandboard and system-on-chip manufacturers.Readers will be able to take their first steps in programming the embedded platforms, using C, Bash, and Python/PHP languages in order to get access to the external peripherals. More about using and programming device driver and accessing the peripherals will be covered to lay a strong foundation. The readers will learn how to read/write data from/to the external environment by using both C programs or a scripting language (Bash/PHP/Python) and how to configure a device driver for a specific hardware.After finishing this book, the readers will be able to gain a good knowledge level and understanding of writing, configuring, and managing drivers, controlling and monitoring applications with the help of efficient/quick programming and will be able to apply these skills into real-world projects.Style and approachThis practical tutorial will get you quickly prototyping embedded systems on GNU/Linux. This book uses a variety of hardware to program the peripherals and build simple prototypes.
